The Exchange

Caption

Bidirectional communication between the nurse cells and the oocyte (one larger cell). Nurse cells send Dap mRNA towards the oocyte (white arrows). In return, the oocyte sends Dap protein towards the nurse cells (yellow arrows). By the end stage of development (largest cells), the nurse cells no longer receive Dap protein from the oocyte.
